To all 'whom it' may concern: lie 1t known that We, ,WILMAM BJ Lener and GRAY SrAUNroNTcitizens oit the United States, both residing1 :it Muskegon., in thecounty of Muskegon and State of l/iichigen74 lieve invented certain new end lisefull1nprovenients in Systems 'for vStoring Fluids Under Pressure? oi which the following. is o specification.

@ur invention relates to improvements in systems for storing iuids under pressure,.

and en automatic inessure. oneretino. valve necessary in carrying our invention into* effect.,

1@ne of tlie objects of our invention is to provide in lisystein iviiereln e plurality ot receptacles ere tooemaintained chargedA oipipes whereby, zitter e receptacle has been so charged itiviil not etten any further resist-ence to the pressure effectingineens untii the pressure Within such receptacle hes Jtellen below the initial pressure.

Another obiect et our invention is to proride en automatically opereting Valve which section ot our eutoniatic veive, showingits' adaptation to spring operation.

inV ail of tile views tlie seme reference characters indicate similar parte,v v Uur invention is especieily designed to meet the requirements Where it is desired to maintain e constancy otpressure in e plurelity ot receptacles in which the medium under compression is supplied by a single source. lt further operates to automaticallyv sliut off each receptacle in turn, as the pressure therein has reached s predetermined value at which the particular valve associated therewith hes been' previously adjusted, and when so shut o yto remove the resisting' edect ot the. pressure of the receptacle so segregated troni the pressure producingA source., Thus when ell of the receptacles lieve been tlius out o-ii"l the pressure producingv source, may continue to operate with practically all oi its resistance or leed rem inoved.7 but' ready to resume its Work when any one or more ot the receptacles have lied its pressure reduced.

For. purposes of complete disclosure We lieve illustrated e Weight adjustable yeive, esssliown in Figs. i end 2, and n spring iusteile valve, essliown initie. Roth of tiiese types of veives ect upon the seine principle end eitlier iorrn may be used in tlie seine situation,

Referring; now to ligs.- i'. and 2; speciiicaiiy. l@ is ecesiinqfprovidedvvitii en intake pipe ogening; iii tor intake pipe i2 und dis cherge openings i3 and 'te bypass pipes i5 and i6 respeetively'te The opening. il is nornieiiy closedu from communication with pipe i5' gravity check valve l?? hingedto tnefeasingt es et l. ielve 19 is normeiiy .ciosed end "shuts on? communication netween openings li end M; The viiive i9 is provided with e veivewsteni 20 which puissesv through e stuiiing box 2l and is slotted through its outer end, :isnt Q2., in axial aiinernent Witli' tiie valve 19' is e cyiinder 23 iornied'in the cesingy; 109' neck ot the check veive l?, conteininge piston 2i, The pis-- ton is provided Witli'e piston stein 25 that passes through e stuil'i'ng non 26 und is siotted through its outer "endg es et 27. A bracket @Sie secured to the cosine and provides a ypivotal sunporti for the team 30. Tlie Weighted loeein or lever impasses through thesiot @Tin tlie piston stern j end carries on its longer end en adjust-able Weight 3l, that is movable along the beam es in e scale or steelyerd,l tli'e olofect of which Wili here stter loe described. A bracket 32 is also secured lto tide casing,F end'gorovides e pivotal support tor-the lever 33., The lever 38. passes tlirougli thesiot 22 in tlie valve stem 20, and

. bese number of pertoretions 3i in the longer extended end'just es the beem@ has perioretions A. link 36 connects tlie levers 30 end 33"by ineens ot pins inserted through the biturcetedends ot' seid link sind through eitlierl ofthe pertorations, ns et 37,' 3'7".

it will loe observed. tiiet when the extended end ofthe loeern 30 is depressed, es by tlie Weight 31, rthe velve 19 is thereby closed, end that the venticeiiyA movable piston 24 is raised end yvalve i9 again opened when the pressure Within that part of the casing with which pipe 15 communicates is suiiicient to overpower the weight, the position-of the weight 31 on the beam 30 therefore controlling the pressure necessary to raise ythe weight.

In Fig. 4 We have marked co-rresponding parts with exponent prime In Fig. 4 there is a spring 31 which is a substantial equivalent of the weight 31 and an adjusting screw 31a is. a means for varying the tension of the spring which accomplishes substantially the same result as moving the weight 31 in and out along the beam 30. A screw cap 3S is centrally threaded for the screw 311l and makes ,threaded engagement with the casing 10 as at 39. It is hollow for a movable follower 40. The follower is bored to provide a guide for the valve stem 20 and it is provided with a projection, 41, of smaller diameter, as a means for holding the spring'31 in place. The follower is moved inwardly by the screw 31a to increase the tension of the spring and is permitted to move 'outwardly to decrease the tension thereof.` A check nut 42 holds the screw in adjusted position. A screw cap 43 permits access to the interior of the casing. ,l

The' use and operation of the device is as follows: In the schematic arrangement, shown in Fig. 3, the tanks are connected by pipes 15, -15a and 15b respectively, and bypass pipes 16, 16a and 16b respectively are connected to the next adjacent valve, and to tanks. Assuming, for illustration, that thetanks are to carryva pressure of 200 pounds, and that the discharge of a liquid pump be connected to pipe 12 and pipe 16b be returned to the lntake of the pump (if economy in the` use o f fluid is not desired, as in the use of water or air as the medium, then the pipe 16b need not be-returned to the pump, but it may end, as shown in Fig. v3) then the operation vwill be as follows: Normally the valves 19 arev closed by thev weights, or springs as the case may be, thepressure upon the valve also tending to hold it closed. When the pump begins to force the fluid medium through pipe 12 the check valve 17 of the irstregulating valve ,(of tank A the others being shut off by valve 19) will open, as shown in dotted lines in Fig. 1, and permit iiow of fluid into tank A a'nd will close with each reciprocation of the pump, as usual with such valves. Fluid will continue to flow into tank A until the .pressure therein has attained the predetermined value, say 200 pounds, then piston 24 will be forced outwardly against the'resistance of weight 31 or spring 31, such Inovement of thje piston serving to open the associate valve 19 and permit luidto flow into pipe 16and from thence into the next adjacent tank B, through the check valve 17 of that regulating valve. In turn the valve 19 of tank B will be opened and tank C will be charged in a similar manner. When valve 19 of tank-C has been opened, in the manner described, then all three of the tanks-are fully charged and the pump will continue to operate through the open passageway established by opening of .the several valves 19. As the passage is open the pump will be doing practically little work, each tank automatically shutting off the resistance pressure from the pump. Should the pressure 'in any of the tanks fall belowy that at which the controlling valves are set, to maintain the respective pressures, valve .19 will'be 'again closed by operation of weight 31, or spring 31 in -moving Athe piston 24 inthe, opposite direction thereby permitting more of the pressure medium to be pumped .into -the tank the pressure of which has been reduced.

AGrreat economy of power is effected by the use of our controlling valves in removing the resisting pressure from the pump as soon as' the desired compression has been reached in the tanks, and thereby also increasing the capacity ofthe pump.

Of course it is o vious that the medium may be Huid, such as air, gas, orv the like,

or a liquid such as water, oil, or the like.

While we have herein fully described a specific embodiment 4of our invention of the preferred form, it is obvious that many changes may be made therein ,within the scope of the claims,'without departing from the spiritof our invention.
